Suppose, I have a list-

 data = {{1, 2, 3}, {3, 5, 0}, {8, 9, 3}, {2, 5, 0}}; 

I want to delete second and fourth row for which third element of the row is zero. I can do this using

 DeleteCases[data,{_,_,0}]; 

How can the same operation be achieved efficiently if the list contains a large number of elements instead of just 3?
